FWIW- I think the fantastic fuel-efficiency and, hopefully, low maintenance of Composite construction, should make this aircraft an absolute winner.
The sheer cost ramifications of the fundamental design flaw in the electrical-system, COULD wipe all that out.
As an aside....there didn't look to be much spare room in the battery-rack for an alternative, lower energy-density technology!
Size/weight although an issue, must be seen in context...
it's effectively a very posh and expensive car battery,
there are only 2 on the entire aircraft.
the weight/bulk difference between proven, robust technology and the Li Co. is miniscule in proportion to the overall aircraft weight/size.
This is the only cutting-edge technology on board which has such disastrous failure mode.
Any competent engineer , left to his own concience, would have prepared a fallback position , in case this EXPERIMENT was a failure.
It was, they haven't , therefore conclusion....office of clueless,arrogant, airhead fxxxwits refused to countenance they could , just maybe, be wrong.
Culpable" management" wants the rough end of a pineapple shoved up their ass and shown the door...they've risked thousands of livelihoods and hundreds of lives.
Just my opinion , of course, so if i'm wide of the mark, I'm awfully sorry, mister caring, coroporate Boeing exec , unlike you I'm retired, on a state pension and worth bugger all so don't bother to sue
